[In-Fluence]

Should be better than the UD3LR in terms of o/cing as I believe it is based on the UD3P. For benching, those extra memory speeds can give you the edge too. Good luck with it!

[DTV DRAGON]

thanx I just installed it and will try it for a few hours before i start to messs with it, It looks alot better made than the ud3lr, nice heatsinks etc, I will post back later as to how well it o/c compared to ud3lr

Hi guys iam having a bunch of problem´s lately putting this setup stable, suddenly this system became unstable and i already tried f4 , f5 ,f7 and f10 bios and nothing .
The program i use is the latest LINX because i think its the fastest to encounter error's.
Some times i get error in 29 test , sometimes in the 175.
The memory passes 4 loops of memtest96.
Already tryng uping the cpu volts, nb voltage to insane values (1.52) running 1000 cas 4 1:1, tried cpu termination voltage @ 1.28 and mch ref @ 0.720 and nothing.
I began to wonder if the system was stable when it crashed and rebooted for no reason this happens maybe 1 time per day, and the game i play battlefield bad company 2 crashes more often than usual.

I know the voltage on the cpu seems low but its a really nice cpu , here are some pics of the day i got this baby (a year ago):



I have been running these settings for a year with no probs.
http://img91.imageshack.us/img91/4508/oc247nn0.jpg
I have an LC power TITAN 560w with full load the 12v drops to 11.85
the 5v line "drops" to 5.0 and the 3.3 "drops" to 3.3

In advance i apologize for my bad english , iam portuguese so easy on me for that
I really apreciate any help you can give me , hope some one figures this one out, cause i can´t.
Thanks .

Ok I have my new ep45t-usb3p o/ced to 4.0 and pretty well useing the same voltages etc. from old ep45t-ud3lr board, I will have to see if i can crank down some of the voltages to get them lower that what i needed before, only thing in bios there is some new things i duidnt have on old board like channel A and B dat vref and channel A+B address vref, the bios setting is .75 on all and i have them all set to normal, is the correct or should i set them to .75 or some other number, overall impression of the board is I realy like it, My system is running abit cooler as well, maybe cause of the better heatsinks?

[Hoss331]

You can either leave the ram references on normal or set them to half of vdimm.

My DX38BT never got my RAM very high for any time, so I switched it out & got the USB3P. I'm running this G.Skill, and trying to get to 1600 on the RAM, and around 4GHz on my Q9550.

Any tips or templates?

Thanks,

using the 333 divider:

Set RAM to 3.20B for 1600 @ 500 FSB

7-8-7-24

4-5-10-74-5-1 (for secondary timings) around 1.5v should do. All vrefs and dram/mch should be .750v

This is good for TRD 8.

CAS 6 will allow you to drop to TRD to 7.

1.34v for both vtt and mch.

[Hoss331]

Is that done with the USB3? On my UD3P the only bios that would allow me to drop down to PL7 on 3.20B and cas 6 was F1 and that was hit or miss. Sometimes it would drop down fine and would prime other times not even able to be set, bandwidth was alot better though but not stable enough to use.

thanx ive always wondered about the secondary timmings Iam still fairly new to o/cing with this board, but so far I love it, alot more stable than the uld3r was I will recheck my ram timmings on next boot as well rais up my fsb more as this board is running cooler as well

Yes, it's the USB3P; incidentally, the bios is also F1. I find that TRCD is the most important setting for stability. Mine won't even post with a TRCD of 6 @ 1600 no matter the TRD setting (1600 CAS 8 Ripjaws here); 6-6-6 is a no go, 6-7-6 is good, but 6-8-6 or even 6-8-7 is better. So generally, TRCD should be equal or 1 unit higher than TRD or two units higher than CAS in some instances if you want to wring every bit of performance from your kits. This is true for the ECOs too.

No problem. For even better stability, you can set TRFC to 88. It doesn't hurt performance.

here is an everest shot of my ram setup now , is it any good?
woops this is with old board i will re run it with this new usb3p board

drop your multi to x8 and raise fsb to 500 and you'll be seeing something close to this without raising your vcore:

Edit: Added more screenshots:
333 Divider, 4.00B for DDR3 2000 1T @ 1.66v, 8-9-8-24 (5-6-10-88-6-1) TRD 8

and

7-9-7-24 (5-6-10-88-6-1) TRD 7

I will be doing some more overclocking and testing later...

[DTV DRAGON]

you think that is the way for me to go to drop cpu multi to 8 and raise fsb.. then if i raise it to 500 that will give me 1600mhz on my ram and thats what i was hopeing for, Am i loseing any performance by dropping the multi to 8? so now i have my timmi9ngs at 7,8,7,24 and sec timmings i set to 5-6-10-88-6-1 like you suggested can I leave those alone and just change the multi to 8? or do i have to loosen the timmings up? , my ultimate o/c i want is 4.0 with 1600 mhz on ram, thats what iam shooting for, let me know what ya think thanx for your help. I realy love these boards I think the problem with the udl3r was it only had a 4 pin cpu power supply and these have the 8 pin wich i think is better than 4 pin ...any truth to that? here is a shot of my ram

Definitely, plus more phases = smoother power delivery to the cpu = better overclocks and less instability.

Yes, leave the memory alone. If your chip/cooling can handle it, you can go for 4.5 (at least for some benches). 9x500 = 4.5GHZ; 8.5x500 = 4.25GHZ (what I'm running); 8x500 = 4GHZ (what your aiming for, and the least difficult to accomplish). I already gave you some tips.

General key thinhs for the best results:

1. Load Bios Optimized Defaults, save and reboot.
2. In the MIT, under advanced cpu results, set skews to

900
900
0
50ps (mch skews). I find that cpu = 100 and mch = 150 works well too. Just make sure mch is always 50ps better than cpu.

Under voltages:

While VTT is set to default 1.200v:

Set cpu vtt vref to .760 and mch vref to 800. The rest is easy, once you get these voltages down. Goodluck.

Yes, it's the USB3P; incidentally, the bios is also F1. I find that TRCD is the most important setting for stability.

This is true for the ECOs too.

I dont want to says its a problem but thats just something these newer kits have to deal with, high trcd. Mine are hypers and dont need/care for high trcd to be stable regardless of PL, there stock rating is 7-7-7 at 1866. Benching wise for SPI 32m I still run them at 6-6-4 so far up to 1740.

Very nice; is that PL7?

[Don_Dan]

Very nice; is that PL7?

Should be PL8, I can only run PL7 up to 495MHz FSB on my EP45-UD3P.

[DTV DRAGON]

hey guys if i change my strap to 4.00b that will set my ram freq to 1784 or close to it. is that way overkill for my g.skills? they are rated at 1600,, when i asked on the g.skill site the guy said they should be able to do it but i will need to loosen up the timming to 8-8-8-22. will there be any benifit to this? or still best option for me is to change multi to 8 and raise fsb wich will in turn get me to my 1600, and will this be good enough for 24/7 use? my temps are actually very good

[Hoss331]

Very nice; is that PL7?

No thats PL8. Thats what I was meaning earlier, PL7 itself was not really stable enough to be used and would only set sometimes and not much past 500fsb. All bios after F1 will not set PL7 at ~500fsb, its only on F1 that it sometimes works.

PL7 above 500 FSB is doable with CAS 6 on the EP45T variant.

Very nice daily settings.

on a side note what bios do you recommend for UD3P? I am running FEa and I felt that maybe FD might be a little bit better on the clocks.

[Hoss331]

I havent played with a 1.6 board so im not to sure which bios it the best on it, mines a 1.0.

[invict]

Found the problem with no help.
Result's:

[al-]

I have been thinking about a northbridge cooling solution, and what's involved in removing the blue top that covers it (the northbridge).

I'm told that it's just attached with double-sided tape, so the question is, would I void the warranty if I removed it?

Has anyone else removed it, and were the results good or bad?

Also, my Scythe Kaze Master Fan Controller has 4-temperature sensor/probes that I never used, could one of them be used with the northbridge, and if so, how should it be applied?

Any thoughts on this, positive or negative are welcome.

My UD3P is r1.6

Thanks-
